As preferably, described brake equipment also includes and can directly be supported in the support portion on described guide rail.
As preferably, described car is connected with counterweight by pulley.
The utility model is provided with check valve at each sections of the delivery pipe of hydraulic oil, make the hydraulic oil only can nonreturn flow, in the time that hydraulic elevator need to hover, only need by liquid feed device, hydraulic control one-way valve to be closed, the hydraulic oil in hydraulic actuating cylinder cannot flow out, and in hydraulic actuating cylinder, remain certain pressure, now car can not cause hovering unstable because of the hydraulic pressure shakiness of liquid feed device, has higher stability.Simultaneously the utility model has also increased on this basis and can make car stop to be stopped at the brake equipment on guide rail, to reduce car pressure to hydraulic actuating cylinder when the hovering, reduces the unavoidable micro-oil impregnate of a whole set of hydraulic efficiency pressure system, further promotes car hoverning stability.
In sum, the utlity model has following advantage:
1, when car hovers, do not need liquid feed device to keep pressure, stability is high;
2, reduce car when hovering pressure to hydraulic efficiency pressure system, reduce the micro-oil impregnate of hydraulic efficiency pressure system.
